Normal Vital Signs — School-age (6–12 years)
School-age children have the widest span in this chart — a small 6-year-old and a nearly teenage 12-year-old differ a lot, so treat the ranges as a band rather than a single target. Blood pressure in particular climbs steadily with height and age across these years, which is why clinicians plot it on charts for the individual child.
| Vital sign | Normal range — school-age (6–12 years) |
|---|---|
| Heart rate (awake, resting) | 70–120 beats/min |
| Breathing rate | 18–25 breaths/min |
| Blood pressure — systolic | 100–120 mmHg |
| Blood pressure — diastolic | 60–80 mmHg |
| Oxygen saturation (SpO2, room air) | 95% or higher |
| Body temperature | 97.5–99.3 °F (36.4–37.4 °C) |
◆ Good to know
Use a correctly sized blood-pressure cuff — a cuff that is too small makes the reading falsely high, which is a common cause of a surprising result at this age.
Measuring at this age
- Blood pressure: right cuff size, arm supported at heart level, feet flat, no talking, after five quiet minutes.
- Resting heart rate is best first thing in the morning or after sitting quietly — not straight after sport or gaming excitement.
- Count breathing unobtrusively for a full minute; children this age often hold or change their breath if they notice.
Fever at this age
A temperature of 100.4°F (38.0°C) or higher is a fever. Thresholds, measuring methods and warning signs by age are covered in the fever guide — and any fever in a baby under 3 months old needs medical care the same day.
